  1. Sorry for the very late reply. The filter arrived with no fitting instructions whatsoever and no help from either the seller or the manufacturer. Fitting it is in no way intuitive and as i didn't want to risk damaging the sensor on a new camera I didn't try. As I'm now changing to a Full Frame D610 I will probably sell it.
  2. Many thanks for taking the time to assist Robin, much appreciated. And of course SC is different to drift alignment. Perhaps we could call it PSPA, an initialism for 'Plate Solving Polar Alignment'. Now all I want is a clear sky. The only clear night we've had recently it was 30°C (86°F) at 2200 and the sky was shimmering like a desert mirage. Today it is grey and drizzling. One thing I have learnt is not to miss an opportunity to shoot when you have good seeing, as those times are rare. Thanks again.
  3. I'm finally ready for first light with my now completed set-up. Completed for the moment anyway. I'm intending to start by imaging with a Nikon D7200. I'm looking for a S/H D600 which I'll get modded. My current lens are Samyang 14mm f2.8 (for the Milky Way etc), Tamron 24-70mm f2.8, Tamron 70-200mm f2.8, Sigma 150mm f2.8 Macro and a Nikon 300mm f4 + 1.4 T/C. I have a HEQ5 Pro with a side-by-side plate to mount the camera, with flash mounted green laser pointer, and my WO 50mm guide scope with ZWO ASI120MM-S to use for drift aligning (?) and when I get into guiding. Initially I'll b
  4. I was googling for someone to do an astro conversion on a Nikon D5300 camera. I was looking at the D5300 because I believe it has a Sony sensor as opposed to the Toshiba variant used in a lot of it's siblings. From my ramblings it seems that the Sony produces less noise than the Toshiba. Anyway I came across this mob in the USA and was interested to read their list of recommended DSLR's for astro conversion. http://www.spencerscamera.com/recommended-cameras-astro.cfm It seems that they have done some work for NASA so one could assume that they know their stuff. As a result
  5. Personally I'd firstly be investigating the capabilities of your current set-up. The shot you posted is not at all shabby for 10 secs. You have a capable tracking mount so why not try tracking and stacking to see what can be achieved with the gear you already have.
  6. If you want to try Photoshop I think CS2 is now available for FREE.
  7. If you don't have it DSS ( http://deepskystacker.free.fr/english/index.html ) is a free stacking program. Open a copy of the final image in Photoshop for PP.
  8. Cheers Tony. I eventually got confirmation from Nikon that the D7200 shared the same filter and light-box as the D7100 and as a result I went ahead and ordered the Optolong UHC Cilp-in filter. Should arrive this week so I will post some pics with and without it.
  9. Hutech have replied that if the D7200 has the same mirror box it will fit. I eventually managed to talk to someone at Nikon Australia Technical Support today, a nice lady whose first language was not English and who I suspect was not even in Australia. I understood most, or maybe that should be some of what she said. Anyway the gist of it appeared to be that the D7200 and the D7100 do in fact share the same sensor, and hopefully the same mirror box. The difference in the megapixels is due to a different algorithm for the D7200 plus the EXPEED 4 processor. I'll bite the bullet a
  10. Cheers Mike. Astronomik only seem to make their filters for Canon so it looks like either Optolong or Hutech. I emailed Optolong on June 22 about suitability for the D7200 but have received no reply. Must have gone in the too hard basket. I've just emailed Hutech so fingers crossed for a better outcome.
  11. Hi, My interest is photographing the night sky with a terrestrial foreground using a DSLR. My prime night sky subject is the Milky Way. Unfortunately, between me and the Milky Way are about 750,000 people and the associated light pollution, see pic below. As my main lens is a 14mm with no filter thread I'm stuck with a clip-in filter. Ive asked in another thread for some help with availability for my Nikon D7200. Would something like the Optolong CLS filter help with the sky glow in the shot below? Thanks Kev
  12. Hi, I've recently acquired a Nikon D7200, mainly for the lack of an OLPF and reasonably good high ISO capability. As I live in an area with moderate light pollution I'd like to get a clip-in LPF as my 14mm lens has no front filter thread. Now these are available for the D7000/D7100 but no specific mention is made of suitability for the D7200, possibly due only to websites not being updated. I've tried to get confirmation from two manufacturers with no reply, and the sellers I've contacted could only come up with 'Should fit'. I strongly suspect that the sensors are the same Tosh
  13. There is a Star Party coming up and they have no stock for a month or more.
  14. After looking into this cable a bit deeper it seems that all DB9 to USB cables are not equal. I don't want to fry the mounts mobo for the sake of 30 odd bucks. To that end I've decided on a HitecAstro EQMOD Direct Adaptor from Rother Valley Optics as FLO wont post to the antipodes. Cheers
